I have now a clear idea of what I want for this Tatooine board. According to the rules, Star Wars Legion games are played on 90 x 180 cm area (3’x6′). I decided to make two 90 x 90 cm area (3’x3′) modules that could be put together on each of their sides. This results in 4 differents configurations for these two modules.
As always, the basic shape of the board topography was made with styrofoam board.
I then covered the whole ground with roughcast.
Once dry, I glued several layer of sand using diluted adhesive.
Next step: painting the rocks, grounds and buildings!
